Federal Tax Brackets 2026

Understanding your marginal tax rate helps you make smarter financial decisions year-round.

Quick answer

The U.S. uses a progressive tax system with seven brackets for 2026: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Only the income inside each bracket is taxed at that rate — your whole income is never taxed at your top ("marginal") rate.
